UV‐ignited frontal polymerization of an epoxy resin
Authors:Alberto Mariani  Simone Bidali  Stefano Fiori  Marco Sangermano  Giulio Malucelli  Roberta Bongiovanni  Aldo Priola
Abstract:By combining frontal polymerization and radical‐induced cationic polymerization, it was possible to cure thick samples of an epoxy monomer bleached by UV light. The effect of the relative amounts of cationic photoinitiator and radical initiator was thoroughly investigated and was related to the front's velocity and its maximum temperature. The materials obtained were characterized by quantitative conversion also in the deeper layers, not reached by UV light. © 2004 Wiley Periodicals, Inc.
